ABSTRACT
Background: Ureterorenoscopy is considered the standard treatment in the management
of urolithiasis with pneumatic lithotripter and holmium: YAG (Ho: YAG) laser.
Aim: To assess efficacy and safety of holmium: YAG
(Ho: YAG) laser lithotripsy in comparison with pneumatic lithoclast during
retrograde ureteroscopy for the management of ureteric calculi of different
sizes.
Methodology:
Data was collected by recruiting 100 patients
of ureteric stone disease admitted in urology department Shaikh Zayed Hospital
Lahore, from 25-02-16 to 15-08-16. All ureteric stone patients of both genders
included in this study were in the age range of 18 to 60 years having stone
size upto 1.5cm.
Results: Stone free rate in Ho: YAG laser group was 94% whereas it was 72% in
pneumatic lithoclast group. The difference in the stone free rate was more
marked for stones greater than 10 mm of size (80% versus 47.4%, P = 0.07).
Overall complication rate was 7.9% (Clavien II and IIIb). There was no
complication found with Holmium: YAG laser. The complication rates were not
dependent on the size of stone.
Conclusion: The use of the Ho: YAG laser in ureteroscopy appears to be a better tool
to disintegrate ureteral calculi independent of stone size.
